ADJUSTABLE YARN WINDER Filed June l, 1938 ATTORNEY Patented Nov. 29, 1938 UNITED STATES PATENT OFFICE ADJUSTABLE YARN WINDER 7 Claims.

This invention relates to new and useful improvements in an adjustable yarn winder.

The invention has for an object the construction of a yarn Winder which is characterized. by an arm adapted to hold a skein of yarn between its end and formed from telescopic sections as hereinafter more fully explained.

Still further the invention proposes the use of resilient means associated with the sections of 'the arm for urging the sections outwards so that the arm is better adapted to hold the skein of yarn.

Still further the invention proposes the provision of a means for rotatively supporting said arm at its center so that it may rotate or oscillate during the drawing off of the yarn.

Another object of this invention is to provide resilient elements adapted to contact with said arm during its oscillation to limit the oscillation in a manner to make it more convenient to draw the skein oi the Winder.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:-

Fig. 5 is a horizontal sectional view on the lino 5-5 of Fig. 4.

Fig. 6 is a fragmentary vertical sectional view on the line 6 6 of Fig. 5.

The adjustable yarn winder, according to this invention, includes an arm formed from several telescopic sections IIJ and II and adapted to hold a skein of yarn indicated by the dot and dash lines I2. A resilient means I3 is arranged within certain of the telescopic sections for urging them relatively outwards. A means is provided for rotatively supporting the arm characterized by a support pedestal I4 having a vertical threaded post I5 upon which the center section I0 of the arm engages. The central section IB is formed with an opening I6 through which the post I5 passes. A ange Il is mounted on the post I5 for the purpose of supporting the arm. The arrangement is such that the arm may oscillate or rotate on the post l5. A

threaded nut cap I5 is provided to engage the threaded portion of post I5 over the telescopic section I0.

The sections and II of the telescopic arm are square or rectangular in cross section to prevent relative turning of these parts without noterfering with longitudinal movements. The outer ends of the outer sections II are formed with curved headed portions Ila adapted to conveniently receive and hold the ends of a skein of yarn. In order to maintain the direction of the head portions Ila, the telescopic sections are arranged non-rotatively as already pointed out.

The ends oi" the section IB of the `arm pass through plates I6 mounted across the open ends of the telescopic sections Il. The extremities of the section l0 are formed with heads Ita which prevent the accidental disengagement of the sections from each other. The springs I3 engage against these enlarged ends ia and the bases of the bores in these end sections.

In Figs. 4-6 inclusive ai modification of the invention has been disclosed which distinguishes from the prior form in the provision of means for limiting the oscillation of the arm. When the skein is drawn off, the arm will naturally be caused to turn rst in one direction and then in the other direction. For the convenience of the person drawing off the yarn it is advisable that the oscillation be limited since if the arm be allowed to turn too far in one direction there is the possibility that the strand of yarn will beco e twisted on the arm.

A bracket 20 is fxedly mounted on the pedestal Ill. This bracket 20 is adapted to be adjusted forwards and rearwards. It is formed with several slots 2I. Clamp screws 22 mounted on the pedestal I4 engage through these slots and by these clamp screws it is possible to xedly mount the bracket as desired. The post I5 projects through an elongated slot 23 in the bracket 2t so as not to interfere with the adjustment of the bracket. At one of the sides the bracket 26 is formed with a pair of vertical tubular sockets 24. These sockets are arranged on opposite sides of the pivot I5. Each socket is threaded and provided with a nut 25. These nuts are formed with openings 26 adapted to i receive a suitable Wrench by which they may be turned.

A vertical leaf spring 21 is mounted through a bushing 28 turnably arranged through an opening in the nut 25. Each leaf spring 21 is frictionally held so that it may be raised or lowered. The upper portion of each leaf spring 2'! is in the path of motion of the arm I and is adapted to limit the oscillation of the arm.

The nuts 25 may be adjusted upwards or downwards so as to change the operative lengths of the upper portions of the springs 2 which are the only portions functioning. It is thus possible to set the springs to a position most suitable for a particular person to draw oif the skein from the yarn Winder.

The operation of the device is as follows:

The telescopic arms of the Winder are compressed and a skein of yarn is engaged across the ends of the arm. When the sections of the arm are released they will be expanded by the action of the internal springs and so the skein of yarn will be securely held. The end of the yarn is drawn 01T and either Wound into a ball or used as required. As the end is drawn, the arm of the Winder will be caused to oscillate back and forth. For each turn of the yarn on the Winder the arm of the Winder will go through one cycle of oscillation.

The springs 2l Willlprevent the arm from oscillating through too great an amplitude which would result in the yarn coming off the Winder much quicker than it should. If it comes off too quickly it Will become entangled about the winder, Which is objectionable.

The bracket 20 may be adjusted to space the springs 2l at various distances from the arm section I U. It is thus possible to control the amplitude of pivoting.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modications coming Within the scope of the invention as defined in the appended claims.
